MANTEL-G RATE.

SPECIFICATION forming part of Letters Patent No 353,043, dated November23,;1 886.

Application filed January 23, 1886. Serial No. 189,547. (No model.)

Beit known that I, EDWARD W. WILLIAMS, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented a new and useful Imp rovenient inMantel-Grates, of which the following is a specification, referencebeinghad to the accompanying drawings, forming a part thereof.

This invention consists of a curved slotted lever connected to the grateand provided with a ball which operates upon a pin, and curved surfacesconnected to the bottom of the basket, all of which will be hereinafterfully described.

In the accompanying drawings, Figure 1 is a plan of my mantel-grate.Fig. 2 is a view in section taken through the center of mantelgrate.Fig. 3 is a bottom plan'view of the grate, its operating-lever, and theaccompanying parts. Fig. 4. is a cross-section through theballand-socketjoint at the inner extremity of the operating-lever.

A is the grate, pivoted within the grateframe B and provided with meansfor end movement for shaking and dumping, as set forth and 'described inmy application for a patent filed June 19, 1885, Serial No. 169,225.-

To the under side of the grate are cast two lugs, G, the. inner faces ofwhich are made slightly concave to receive the ball D at the end of thecurved lever. Said ball D is conveniently supported between the curvedsurfaces by means of a horizontal transverse pin,

The operating-lever E is slotted and curved upward, as shown, andoperates upona pin, F, the latter being supported by a right-angled lip,G, connected to the lower edge of the grate-basket, and the edges ofboth the rightangled lip and basket are rounded, so thatthe slotted andcurved operating-lever will'slide freely without coming in Contact withany sharp angles. The upper and lower faces of the ball at the end ofthe curved lever are slightly flattened for convenience in introducingthe ball to its socket, and this is accomplished by turning theballflatwise, so that the flattened surfaces can be first introduced andthen turned within the socket, in which position the'rounded portions ofthe ball will act in the concave portions of the lugs.

In practice it will be observed that by operating the lever to and frothe grate is shaken as well by this device as bytmy former inventionhereinbeforementioned so that a shaking as well as dumping grate iscombined in one and the same device, and by pressing or bearing thecurved lever downward by the projecting arm H the grate is quickly andeasily dumped, the curvature of the lever being of such an are as tocarry the grate backward toward the chimney or masonry of the fire-placebeyond a perpendicular and effectually clearing the grate of all debris.

Having thus described my invention,-whatI claim, and desire to secure byLetters Patent, 1s

1. The combination of the grate frame B, provided with lip G, having apin, F, the dumping-grateA, pivoted in said frame and provided withdownwardly-extending lugs O (1, whose opposing faces are .concaved, andthe curved and slotted operating-lever E, movable on the pin F andhaving a terminal ball, D, held between the lugs G, substantially asdescribed.

2. The combination, with the grate-frame B, having lip G, Supporting thepin F, and the dumping-grate A, pivoted in said frame and provided withlugs G 0, whose opposing faces are concaved, of the curved and slottedlever scribed.

i In testimony that I claim the foregoing I have hereunto set my handand seal.
